Parameters and associated values used in population equations 1 and 2 (NA = Not applicable; Temperature-dependent sex determination (TSD))
| Parameter description | Symbol | Default value | Range of values (if applicable) | Source |
|---|---|---|---|---|
| Annual adult survival | s | 0.95 | NA | Congdon et al. (1994) |
| Baseline embryonic survival | a | 0.015 | 0–0.015, depending on temperature | Heppell (1998) |
| Number of offspring (eggs laid) per adult female | B | B max , 10 | 0–10, depending on male limitation | We chose the value 10 to produce a stable population (no male limitation) |
| Proportion of hatchlings that develop as male | p | 0.5 | TSD: 0–1, depending on temperature GSD: 0.5 |
Bull (1980) |
| Parameter for density dependence in embryonic survival | c | 0.001 | NA | We chose this value to produce a low effect of density dependence |
| Air temperature (°C) | T | 16–35°C | Birchard (2004) |
